Karate Kiba (1973) tells a story of a Karate master and anti-drug vigilante Chiba who returns to his home in Japan. He holds a press conference and announces his intention to wipe out the nation's drug industry. He also offers his services as a bodyguard to anyone who is willing to come forward and provide information about the drug lords' activities. He is soon approached by a mysterious woman claiming to have important information and asking for Chiba's protection. She seems to be legitimate, but is she really what she appears to be?

Sonny plays himself and offers himself to be a bodyguard to anyone who knows about the flood of illegal drugs. Surprislingly, this is one violent film. All of the butt-kicking of the Streetfighter with the action of 5 martial arts films rolled into one.
